Yes, humans are animals in the biological sense. We belong to the kingdom Animalia, which includes multicellular organisms that consume organic matter, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. This classification is grounded in a scientific understanding of our physiology and evolutionary history. Our unique cognitive abilities and complex societies sometimes obscure this fact in philosophical or cultural discussions, yet biologically, we share much with other animals.
